目的　观察儿童外伤性白内障在伤后不同时期内行人工晶状体 (IOL)植入术的术后视力及并发症 ,探讨儿童外伤性白内障的手术时机。方法　对 43例 (43眼 ) 2岁以上儿童的外伤性白内障在不同时期行IOL植入术 ,比较各时间组手术的远期疗效。结果　 43眼术后随访视力≥ 0 5者 2 3眼 ,占 53 49%。伤后 5～ 1 5天手术者 1 0眼 ,视力≥ 0 .5者 4眼 ,占 40 % ;1 6～ 30天手术者 2 1眼 ,视力≥ 0 5者 1 3眼 ,占 61 94% ;30天以上手术者 1 2眼 ,视力≥0 .5者 6眼 ,占 50 0 %。结论　儿童外伤性白内障伤后 1 6～30天行IOL植入术远期视力稳定 ,并发症较少 ,是较为理想的手术时机 Objective To observe postoperative visual acuity and complications of intraocular lens (IOL) implantation in children with traumatic cataract and to explore the timing of surgery in children with traumatic cataract. Methods Forty-three children (43 eyes) with traumatic cataract who were over 2 years old underwent IOL implantation at different time points. The long-term results of the operation were compared between the two groups. Results 43 eyes were followed up for visual acuity ≥ 0 5 23 eyes, accounting for 53 49%. 5 ~ 15 days after injury, 10 cases of surgery, visual acuity ≥ 0 .5 4 cases, accounting for 40%; 1 6 ~ 30 days surgery 21 eyes, visual acuity ≥ 0 5 13, accounting for 61 94% ; More than 30 days surgery 12 eyes, visual acuity ≥ 0.5 5 were 6, accounting for 50%. Conclusion IOL implantation in children with traumatic cataract after 16-30 days has long-term visual acuity stability and less complications, which is an ideal timing for surgery
